Driving home tonight I notice that the inside of my car is freezing.So I do what any normal person would do and turn on the heat.I select the heat to come from the de-frost vents.I can see out my windshield now so I select the heat to come out the front vents to now warm me and the kids....only no air flow from those vents.It is still coming out the de-frost vents.I soon realize that every selection made, air is only coming out the de-frost vents.
It will not change to floor, front vent, floor/vent .... ONLY de-frost vents.I turn on the A/C even though it is cold as ice out but wanted to see what would happen.Same thing.It comes only from the de-frost vents.

TCCA,
Couldn't this be a 'blender door' problem (maybe blendor door actuator is the correct term)? I know that mine failed about a year ago and defrost is where the blender door stopped on.

You can do a test to see if it is indeed the problem. Turn off all noise (i.e. radio) and turn the knob from defrost to vent to floor. You should hear a 'popping' noise or some movement behind the dash. This is the blender door turning to focus the air to the correct spot/setting.

Vacuum lines are behind the heater controls. You will have to remove the radio to get access to the vacuum line bundle. Ignore the red circles around the small screws, I took this pictures from a write up that I did in the wiki.

Ok so I removed the radio and released the hose connection.
Now what do I need to look for? I blew into the little connector and I could not blow air into it.I will assume that means no leaks, or does the air need to be running?
I cant see any cracks and can so far only see to the firewall.I have yet to see it in the engine compartment.It's raining to day.

You may have to check under the hood for a vacuum leak. A hose may have unhooked causing no vacuum to be applied to the HVAC system.

I will also mention just for your knowledge if you didn't know, the reason the air is coming from the defroster only is a system default. When the system loose vacuum, it will automatically send air flow to the windshield to the window is kept clear. Thought I'd mention that since it wasn't mentioned already. If I can find the vacuum diagram tomorrow I will post it up for you. I have access to ALLDATA at the college where I'm working on my second block. I will see if I can find you the diagram, unless someone else has it already.
